After falling flat from a mile high with only a parachute still wrapped in a burrito, one Vulcanite fin took the brunt of the impact bending at the root about 15 degrees. The wood failed along the grain but did not separate. The first thought was to wiggle the fin back and forth until it broke of and then epoxy it back together. On second thought, with all the fibers sticking up, the chance of getting a good fit was considered minimal. So, on a whim, I decided to just inject thin CA glue into the seam on both sides. The thought was that the CA would wick up into the voids between the separations in the grain creating a strong bond.
I will likely test fly the repaired Vulcanite on a G motor to keep forces low but would like to take full advantage of the 38mm motor mount if the fin will hold up. Does anyone have experience with how strong a 1/8 inch birch ply fin is after being CA'd like this?
